AT NEYSH NITED STATES I PATENT OFFICEO JOHN R. PAYNE, OF FREEDOM, INDIANA.

SPECIFICATION forming part of Letters Patent No. 297,841, dated April 29, 1884.

Application tiled March '18, 1884.

T0 coZZ whom it may concern:

Be it known that I, JOHN R. PAYNE, a citizen of the United States, and a resident of Freedom, in the county of Owen and State of Indiana, have invented certain new and useful Improvements in Sawing-llfachines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which. form a part of this specification, and in which Figure 1 is a side View of my improved sawing-machine. Fig. 2 is a similar view of the same, seen from the other side. Fig.3 is a top view, and Fig. 4 is a detail view.

Similar letters of reference indicate corresponding parts in all the figures.

Myvinvention has relation to that class of sawing-machines in which the power to reciprocate the saw is derived from a person rocking a lever having handles and foot-rests at its opposite ends with his hands and feet; and, it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates a rectangular frame, the top pieces, B B, of which extend beyond the ends of the frame, and form handles by means of which the machine may be transported from place to place, and form transverse bearings 0 near the rear end of the frame, in which rocks a transverse shaft, D, upon which the hand and foot lever E is secured at its middle, which lever is provided with a foot-rest, F, at its lower end, and with a transverse handle, G, at its upper end, by means of which the lever may be rocked by a person sitting in the seat H, which is secured in the rear end of the frame. A pitman, I, is hinged at one end to the lower end of the hand and foot lever, and is hinged at its other end to a double crank,

J, upon a shaft, K, journaled in transverse bearings L L in the sides of the frame, which shaft is provided with a cog-wheel, M, at one end, which meshes with a pinion, N, secured upon a shaft, 0, journaled in transverse bearings P in the sides of the frame, and provided (No model.)

in horizontal ways V, formed upon the outer 1 sides of the top piece and bottom piece of that side of the frame, allowing the end of the pitman to be raised or lowered. The outer side of the rear end piece of this rectangular sliding frame is provided with a flange, W, T- shaped in crosssection, upon which flange a block, X, having a Tshaped recess, Y, slides, and may be adjusted by means of a set-screw, Z. The rear end of the saw-bearing bar A is pivoted to this block, and the saw B is secured in the end of the saw-bearing bar, and has the corners of its lower toothed edge rounded, so as not to drag objects upon the ground if the frame is moved and the saw is not raised. The outer portion of the sawbearing bar slides in the lower end of I a long frame, 0, provided with an anti-friction roller, D, at its lower end, upon which the saw-bearing bar slides, and is secured upon the end of a bar, E, pivoted at its rear end upon the upper side piece of the frame upona bolt, F.

A lever, G, is secured upon the inner or rear end of the frame-bearing bar, and is provided with a pawl, H, operated by means of a handle and rod, 1, which pawl engages a ratchetsegment, J, upon the top piece of the frame. Two dogs, K, are hinged to the forward end of the frame,and two rods, L, slide in bails upon the rear uprights, M, of the frame, having their upper ends bent at a right angle, adapting them to rest upon two pegs, 0, upon the inner sides of the uprights when the rods are raised.

It will be seen that the frame may be secured upon the ground by forcing these rods into the ground, and that the log or wood-jack or saw-horse may be held by the dogs; and it will also be seen that the saw may be loweredor raised by means of the lever and the framebearingbar, while the angle of the saw while sawing may be adjusted by sliding the block having the T-shaped recess upon the flange of the rear end piece of the rectangular sliding frame.

anti-friction roller at its lower end adapted to have the saw-bearing bar sliding upon it, and

having means for raising or lowering the bar,

as and for the purpose shown and set forth.

In testimony that I c1aim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

JOHN R. PAYNE.
